ProAnimator is freezing After Effects

I just got a Mac Pro and installed ProA to use in a commercial.
When the time came, I set the text and when I clicked the ProAnimator Edit button, the windows for ProA come up, and then ... just flicker and flicker. They don't even have all their contents filled in yet. The timeline and a couple other items, the rest is blank. And the Title bar on the ProA timeline window keeps flickering. I can close it and I have to force quit AE just to get out of it all.

Any ideas? I admit I've been messing with different settings to get AE to move as fast as it can, toggling multiprocessing on an off and trying different settings. Is there something I should avoid if I want ProAnimator to behave?
